The Berlin-based firm’s founder and CEO Christian Reber made the announcement in a blog post on the Wunderlust website on Tuesday after news of the deal leaked out.

Reber says, in rather predictable fashion, the purchase isn’t the beginning of the end for Wunderlist, but the chance for the firm to fulfil its ambitions.

On the post, he wrote: “Our aspirations are much bigger. Joining Microsoft gives us access to a massive wealth of expertise, technology and people that a small company like us could only dream of amassing on its own.”

So, basically the popular to-do list app it’s not being folded into Outlook or OneNote yet, which is good news for the 13+ million users who have amassed over a billion to-dos.

“So what will change for you?” Reber writes, “Nothing right now. Our team in Berlin will continue to build and deliver you Wunderlist, Wunderlist Pro and Wunderlist for Business across all platforms.”

“Over the next few months as Wunderlist becomes a part of the Microsoft family, we’ll introduce a host of new features, continue growing the ecosystem of partner integrations and progress in delivering Wunderlist to billions of people.”

The news that third-party integrations will still be supported – and indeed expanded – is good news for Wunderlist loyalists, while it’ll surely become a bigger part of Microsoft’s own productivity suite in due course.
